+The Turn tail reads the proposals of the `pluginRecommendations` Session projection and shows the one admitted in its Turn once that Turn has ended, for any end reason; the projection admits at most one proposal per Turn, and the chat hides the fence itself. A proposal the projection marks never offered renders nothing. The card asks the Host for the plugin's current catalog text and selection; a name outside the eligible catalog shows no actions. The browser contribution keeps returned catalog text by plugin name for its lifetime, so a revisited card renders it at once while its own lookup refreshes the selection. Until a plugin's first lookup returns, placeholder lines and the disabled actions hold the title, description and footer in place. Session projection decisions drive the card after reload. The optional Remote and all UI registrations are removed together on unload.
 
 Cards use the application font, the deliverables card border and background, a distinct title and compact body scale, and a separate action footer. The built entry supplies generated Remote descriptors to the source-tested mount lifecycle.
